DUST-PROOF INK-WELL COVER...

Specification of Letters Patent.

Patented June 19,1906.

.To ail-Z whom it may concern.- I

Be it known that I, "J OHN'KASTNER, Jr., a

citizen of the United. States, residing at Evansville, county ofVanderburg, and

State of Indiana,have invented certain new and useful Improvements inDust-Proof Ink- Well Covers, of which the following is a speci- Thisinvention relates to dust-proof ink well covers, and moreparticularly'to those adapted to be attached to a school or other deskhaving a sunken ink-well.

The object of the present invention is to provide an improvement on theink-well cover set forth in my cop'ending applicationfiled May 18,1905,Serial No. 261,026. Inthat] application there is disclosed andclaimed an improved dust-proof ink-well cover having a frame of twopieces of sheetmetal which may be soldered or connected together, onewithin .the. other, to form-"a guideway or loosely fitted within eachother and held together when the device is screwed to the school orother desk. The invention disclosed in that application also embodies asheet-metal flanged cover slidable' between the frame-pieces and adaptedto open or close openings in the frame which register with the mouth ofthe usual ink well, which is sunk in the desk in a well-known manner.

The present invention has for its object the provision of improved meanswhereby the parts of the frame and the sliding cover will always be keptsnugly associated, so that the cover will always exclude dust from theinkwell when closed, and the present improvement obviates thenecessityof soldering or connecting the parts of the frame together tomaintain a tight fit between the frame and covler, and thus'exclude dustfrom the inkwel The invention is set forth in detail hereinafter and thenovel features are recited in the claims.

In the accompanying drawings, Figure 1 is a plan view of the inventionin use; Fig. 2, a longitudinal section of the device removed from thedesk; Fig. 3, a cross-section; Fig. 4:, a detail view of the respectiveparts of the frame shown detached; Fig. 5, a perspective.

of the inner part of the frame, showing the spring; Fig. 6, a detail ofthe sliding cover, and Fig. 7 a detail of a modified form of slidmgcover.

The numeral 1 designates the top of an ordinary school-desk, which isprovided with top of the desk. The inkwell cover conthe inner part 4,and the slide or cover 5, all

3 'has a raised portion 6, provided with a circular opening 7 of aboutthe same size as the ink-well 2 and provided with'dia'metricallyopposite notches 8 and 9 The outer part 3 also i has a flange 10,provided with screwholes 11, by which the device may be screwedgown'tightly on the desk, so as to exclude all u'st. corresponding tothe opening 7 ,'and it is provided with the flanges 12 and fits into theraised portion 6 of the outer frame member? This provides a space orguideway between which has the side and end flanges 5 causing it tofittightly, and yet be adapted for movement between the outer andinner'parts to the ink-well, and there'are no projecting partsto beinjured or, broken. The slide 5 is provided with "a finger-hold 15,adapted to engage either of the notches 8 or 9 and formed by bending upthe material. The flange 5 may be provided with a lateral offset portion5 as shown in Fig. 7 ,if preferred. As thus set forth, the constructionis in all respects similar (with the exception of flange 5) to thatdescribed and claimed in my application filed May 18, 1905, Serial N 0.261,026. In that application I stated that the frame parts 3 and 4 mightbe connected together by soldering or by lips or otherwise, and whilesuch connection was not essential or fastening together of the parts 3and 4 is entirely unnecessary.

To carry out the present invention, one or more springs are employed tohold the frame part 4 firm y and yet yieldingly against the cover 5 andframe part 3, so that a tight the usual ink-well ,2, sunk therein belowthe sists of a frame composed of the outer part 3 The-inner part 4 hasan opening 7 it rendered the device more nearly dust-- proof. With thepresent invention soldering of which are of sheet metal. Q The outerpart a the parts 3 and 4 for the slide or cover 5,

3 'and 4. Thetight fitting of the slide or cover'5 absolutely preventsthe access of dust joint isalways had and dust absolutely excluded. Thespring may be placed in any desired position on any of the parts toaccomplish the desired result, and it may be separately formed or struckup as a spring-tongue from the part on which it is located, and Idistinctly Wish it understood that I do not limit myself to an integralor non-integral spring or to a spring placed on any particular part ofthe device or in any particular position, provided it will accomplishthe function sought after; nor do I limit myself to the use of a singles ring, as a plurality of springs may be emp 'oyed. V

The invention may be conveniently carried out by striking up aspring-tongue 25 from the frame adapted to bear against the desk 1 w enthe entire device is assembled and by its compression hold the part 4firmly against the cover 5 and also against the part 3.. The cover 5 isthereby snugly associated with the parts 3 and 4, free to be slid tocover or uncover the ink-well, and all dust is excluded from theink-well 1.

Having thus described my invention, what I claim as new, and desiretosecure by Letters Patent, is

1. In an ink-well cover or closure attachment for desks, the combinationwith a guiding-frame adapted for attachment to the desk, and a cover orslide guided by said ,guidin frame and adapted to close the inkwell, 0spring means adapted for holding the cover or slide in yielding slidableengagement with the guiding-frame.

2. In an ink-well cover or closure attachment for desks the combinationwith a twopart guiding-frame adapted for attachment tothe desk, and acover or slide positioned between the arts of said two-part guidingframeand a apted toclose the ink-well, of

spring means adapted to insure a yielding part 4, said sprin being.

to the des slidable engagement of the cover with the guiding-frame.

3. In an ink-well cover or closure attachment for desks, the combinationwith a twopart guiding-frame adapted for attachment to the desk, saidframe having its parts loosely associated, and a cover or slidepositioned between the two parts of said frame and adapted to close theink-well, of spring means adapted for pressing the frame parts and theslide or cover together.

4. In an ink-well cover or closure attachment for desks, the combinationwith a guiding-frame composed of outer and under parts, the outer partbeing adapted for attachment to the desk and the under part lyingagainst the desk, said parts bein loosely associated, and a cover orslide positioned between the outer and under parts of said frame andadapted to close the ink-well, of a spring interposed between the underframe part and the desk and adapted for pressing the frame parts and thecover together.

5. In an ink-well cover or closure attachment for desks, the combinationwith a guiding-frame composed of outer and under parts, the outer artbeing adapted for attachment if and the under part lying against thedesk, said parts being loosely assoclated, and a cover or slidepositioned between the outer and under parts of said frame and adaptedto close the ink-well, of a spring secured to the under frame part andbearing against the desk, said spring being adapted for ressing theframe parts and the cover toget er.

In testimony whereof I hereunto aflix my signature in presence of twowitnesses.
